Alarm Detection

A block alarm will be generated whenever the BLOCK_ERR has an error bit set. The types of block error for the resource block are defined in Table F-2.

A write alarm is generated whenever the WRITE_LOCK parameter is cleared. The priority of the write alarm is set in the following parameter:

•WRITE_PRI

Alarms are grouped into five levels of priority, as shown in Table F-3.

Table F-3. Alarm Priorities

Priority
Number	Priority Description
0	The priority of an alarm condition changes to 0 after the condition that
	caused the alarm is corrected.
1	An alarm condition with a priority of 1 is recognized by the system, but is
	not reported to the operator.
2	An alarm condition with a priority of 2 is reported to the operator, but
	does not require operator attention (such as diagnostics and system
	alerts).
3–7	Alarm conditions of priority 3–7 are advisory alarms of increasing
	priority.
8–15	Alarm conditions of priority 8–15 are critical alarms of increasing priority.
